Please help it's thermal energy in science

the link still does not work even when adding it to the url bar

explanation:

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

it is stable as it is in group 0 which have full outer shells of electrons
